研究成果

In summary, we demonstrate a hybrid energy harvester composed of a Si-based solar cell and a WD-TENG in this work, which could harvest energy of sunlight and raindrops depends on the weather conditions. The introduction of a nw-PDMS coating layer onto the surface of the solar cell reduces the reflection of the incident light, thus enhances the absorption of the light inside the solar cell and further improves the energy conversion efficiency of the solar cell from 12.55% to 13.57%. Furthermore, the utilization of the bi-functional nw-PDMS coating layer could enlarge the working condition of the solar cell by serving as the triboelectric layer of the WD-TENG to collect the raindrop energy, which is a beneficial complement for the solar cell. The VOC-T and ISC-T of the nw-PDMS based WD-TENG are enhanced by 385.5% and 299.1%, respectively, comparing with the p-PDMS based WD-TENG, which is attributed to the nano-wrinkled structures and hydrophobicity. This work provides a strategy for developing high-performance hybrid energy harvester with simultaneously enhanced ability to collect the energies from sunlight and raindrop. Moreover, due to the facile preparation route, the methodology could be easily transferred to all other type of solar cells without any barrier, showing great universality and broad application prospects.
